We have rooms blocked off for wedding guests at a hotel in Hveragerði called the Frost & Fire Hotel. Technically speaking, you don't have to stay here. But since it's the launchpad for all wedding activities, as well as the location of the reception, it's recommended that you get a room here. In addition, while there you'll experience the wonderful Restaurant Varmá (you're going to want to try to carrot cake; trust us), where you can grab breakfast during your stay.
Frost & Fire Hotel
Hverhamar, 810 Hveragerði, Iceland
Note that if you are attending the wedding and plan to stay at the Frost & Fire Hotel, you need to perform your booking through the RSVP form. Don't worry: it's no money down, pay at checkout.
